To all whom it may concern:

Be it known that I, WTLLIAM A. KILMER, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Im rovements in Barb-Wire Machines and Ido liereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same.

rI`his invention has reference to a machine for the manufacture' ofbarb-wire. It has articular reference to the manufacture of aybarb-wire, wherein the barb is pivotally supported upon one of thestrands of a double or twisted Stringer-wire at points thereon where thestrands are separated or one of them eX- panded, providing space topermit the free turning of the barb and to prevent impingement thereof.Reference is had to the patent issued to F. C. Carroll, for improvementin barbed wire, dated Dec. 5, 1899, No. 638,320, wherein is shown abarb-wire and one of the forms which may be produced by this invention.

The invention has for its object a coiler through which is fed astrand-wire, means for feeding and supplying a barb to said strand, anda member reciprocally carried in the coiler through which the strand isfed, adapted at pre-determined intervals to be projected along thestrand to properly position or place the barbs as they are formed on thestrand.

A further object of the invention is, a c'oiler, through which is fed astrand wire, means for feeding a wire to the strand and forming from itbarbs, a member reciprocally carried in the coiler adapted to beprojected through the coiler for properly positioning or placing thebarbs as they are formed on the strand, and a carrier, traveler orconveyer` adapted to convey the strand and while doing so retain thebarbs thereon in the position placed by the member in the coiler.

The invention has for its further object a coiling member, a strand ofwire adapted to be fed through the coiler, means for feeding a wire tothe strand to be coiled by the coiler into barbs on the said strand, acutter for severing the wire as the barbs are formed, means reciprocallycarried in the coiler adapted to slide the barbs on the strand, acarrier having gripping members adapted to draw the strand through thecoiler and to receive the barbs in the said gripping members, means forfeeding a third wire adapted to be intertwisted with the barbed strand,and means for corrugating or kinking the said strand where the samecoincides with the barb of the strand with which it is intertwisted.

A further object of the invention, is a coiling member through which. isfed a strand wire, means for feeding and placing a barb on the aforesaidstrand, severing devices, and a continuous traveler provided withgripping members or vises adapted to draw the strand through the coiler,and the vises thereof arranged at stated intervals thereon to receivethe barbs and retain them in their proper positions on the strand, awrapper supporting a spool on which the finished barbed-wire isMfOund, afriction brakefor regulating the tension of the wire as it is wound onthe spool, and means for automatically and at pre-determined intervalsreleasing the brake.

To these ends my invention consists in the features and in the novelconstruction, combination and arrangement of parts hereinafterdescribed, and particularly pointed out in the claims following thedescription, and while `the essential and characteristic features of myinvention are necessarily susceptible of modification the preferredembodiment thereof is illustrated in the accompanying drawings, in whichFigure 1 is a side elevation, on a greatly reduced scale, of a machineembodying my improvements; Fig. 2 is an elevation on a greatly reducedscale, of the opposite side of the machine seen in Fig. l Fig. 3 is aplan view of the machine shown in Figs. 1 and 2 Fig. 4 is an end view ofone end of the said machine; Fig. 5 is a sectional elevationillustrating the friction brake, the feed for the barb-wire, and thearrangement of the cutter su ports, and means of operating the movab ecutter; Fig. 6 is a longitudinal section through the coiler, showingalso, the arm for operating the plunger therein, and operative parts indotted lines positioned at the ceiling end of the said coiler; Fig. 7 isan elevation showing in cross-section the coiler and plunger therein;also the cam and arm actuated thereby for operating the feed for thewire forming the barb Fig. 8 is an elevation, showing in detail a guidearranged in front of the ceiler, and the means of moving the same fromthe path of the barbs as the same are formed 5 Fig. 9 is a sideelevation, partly in section, showing the traveler and its clampingmembers or vises for receiving the barbs and for drawing the strandthrough the coiler the view shows further, the end of the coiler insection and the means for crimping the second wire forming the twistedbarb strand Fig. 10 is a plan in detail of the links forming thetraveler and the clamps or vises attached thereto, Fig. 11 is a sideelevation of Fig. 10 Figs. 12 and 13 illustrate in crosssection thedetail construction of the links and clamps or vises seen in Fig. l0,Fig. 14 is a bottom plan of a section of the traveler taken at a pointwhere the wires leave the same to be intertwisted to form the cable g itfurther shows, the manner of causing the clamps or vises to firmlyimpinge the wires to enable the same to be intertwisted as they leavethe traveler.

Like numerals of reference indicate correspending parts throughout thefigures.

e working parts of the machine are mounted or su ported on a bed framel, supported by the egs or standards 2.

3 denotes a driving shaft supported longitudinally of the machine abovethe bed l and journaled in the boxings 4, 5 and 6 secured to the saidbed. The manner of driving the said shaft is through an endless sprocketchain 7 receiving its power from a driving sprocket wheel 8 on a powershaft 1() and communicating it to the shaft 3 through a sprocket wheel11 carried thereon. The power shaft 10 carries a pulley wheel 12 whichis fast thereto, and a loose pulley wheel 13. Power is imparted to thepulley wheel 12 by means of a belt (not shown) receiving its power froma suitable source, which is shiftable by means of a shifter 14 adaptedto be actuated by means of a hand lever 15 pivotally secured to the bed-1 and connected with the shifter by means of a rod 16. The shifterserves as a means to throw the belt from the fast to the loosely carriedpulley wheel or vice versa as desired, producing a result well known.

The ceiling devices, the manner of feeding a strand thereto and drawingthe same therethrough, as well as the means for feeding barbs to thestrand will new be described: 17 indicates a ceiling spindle journaledin the front and rear boxings 18 and 18il supported by the standards 19lof a casting 19 secured to the bed. The spindle is formed with alongitudinal bore of two different diameters, 20 and 20a. The ceilinghead of the spindle is indicated as 21 which is suitably secured to theinner end of the spindle, is provided with a central wire opening 21a,and eccentrically disposed in the face of the head is secured a pin 22projecting therefrom a suitable distance.

Carried and reciprocally arranged in the spindle is a tubular stem 23,and when in its normal position the inner end is disposed in the opening20a of the spindle, the same having an extension projecting forwardly ofthe end of the spindle which is attached to means for reciprocating thesame. To the inner end of the stem 23, is secured the end of a plunger24 which extends through the opening 20 of the spindle and has itsforward end carried in the opening 21a of the head. In its normalposition the end of the plunger is iiush with the face of the ceilinghead. And the plunger is provided with a wire groove or opening 24awhich communicates with the opening in the stem 23. The manner ofreciprocating the stem and plunger through the ceiling spindle, forpurposes which will be more fully described, is by means of a crosshead25 to which the outer end of the stem 23 is secured, and attached oroperatively connected with the head 25 is the inner end of an arm 26,the outer end of which is fulcrumed or pivoted at 26a, to a support onthe bed. Intermediate its ends, the arm- 26 carries a roller 27 disposedand movable in a groove 2SEL of a cam wheel 28 attached to the drivingshaft 3. The connection between the inner end of the arm 26 and thecross-head 25, is through a iianffed pin or roller 29 which eperates inan e ongated or longitudinal slot 29"L of the arm, to give free movementto the arm across the axis of the stem 23 as the same is oscillated toshift or reciprocate the stem and the plunger. The cross-head is guidedor held to its work by rods 30 lying parallel and upon opposite sides'ofthe stem 23, their forward ends connected to the standards 19a, theiropposite ends passing through the cross-head 25 and connected by a strap30a.

The wire strand upon which the barbs are placed will be indicated as A,and is fed from suitable spools or reels, not shown, through `a guide 31to and around a roller or wheel 32 rotating under tension, and from thewheel 32 the wire is directed through the stem 23 and the plunger 24, tomeans for drawing the strand through the stem and plunger and feedingthe same to a suitable wrapper.

The wire strand from which the barbs are formed will be indicated as B,and like the Wire A is fed to the machine from suitable spools or reels,not shown. The wire B is fed or drawn between feeding rollers 33,secured respectively on the ends of shafts 33aL and 33b journaled in astandard 34 supported on the bed. The manner of actuating the feedingrollers 33 is as follows: On the ends of the shaft 33EL and 33h,opposite to the ends which. carry the rollers 33, are carriedintermeshing gears 35. The shaft 33b carries a ratchet wheel 36 adjacentto the gear 35, and coacting with the teeth of the ratchet wheel is apawl 36a carried by an arm 37 fulcrumed on the shaft 33h. To the lowerend of the arm 37 is pivotally attached the inner end of a bar 38, theouter end of which has a bifurcated portion 38a, the extensions of whichare movable across the axis of the shaft 3 and retain the end of the barin working position with operative parts on said shaft, On the shaft 3is carried a disk 39 provided with a cam groove 39a in its face, l

in which is adapted to travel a roller 40 secured to the bar 38. Thus itwill be seen, that the continued rotation of the shaft 3 will, throughthe disk 39 and the ratchet and pawl connection with the grooved wheelsor rollers, intermittingly actuate the same to feed the proper length ofwire B to form a barb, and at the proper intervals of time.

The wire B is carried from the feeding rollers 33 through a cutter 41,carried in a stationary support 41a. The said cutter is disposed at aproper angle with reference to the feed of the wire B to the coilinghead to adapt its pin 22 to direct the wire B as it crosses the strand Ain front of the coiler, around the said strand, somewhat in the mannerseen in Fig. 15. Forming a loose barb as 1 do, the Wire B is coiled oncearound the strand A and fed in such lengths that one side of the barb ispreferably longer than the other side.

1 have provided for holding the end of the wire B, adjacent to the faceof the coiling head 21, during the coiling of the barb, by means of anoscillating member or finger 42, fulcrumed at 42 to a suitable supporton the bed 1, its inner end extending partially across the face of thehead 21, and grooved at 43, to form a seat for the wire` A, whichextends therethrough. The outer end of the finger 42 rides on theperipheral edge of a disk 44 havingI a cam surface 44a, adapted atpredetermined intervals to raise the outer or engaging end of the finger42 and correspondingly lower the inner end of the said finger out of thepath of the formed barb on the strand A. Immediately on the moving awayof the cam surface of the disk 44, the finger is returned to its normalposition through the action of a coil spring 45, one end connected tothe inner end ofthe finger, its opposite end connected to a support 45atsecured to the boxing 18, see Fig. 8. The feeding rollers 33 and the'linger 42 are timed in their movement to the action of a movable cutterwhich is brought into play immediately upon the formation of a barb,which is the coiling of the end of thetwire B around the strand A.

The movable cutter is indicated as 46 adjustably mounted in a plate 47,the adjustment being secured through a threaded stem 4S and alock nut48a. The plate 47 is secured to or may form a part of a verticallydisposed plunger 49 extending through the bed 1 and a bearing or sleeve50 secured to the said bed. To the lower end of the plunger 49 isattached a bar 51 fulcrumed at 51a, and its outer end pivotally attachedto a bar or member 52 which has a bifurcated end 53, the extensions ofwhich are movable across the axis of the shaft 3 and adapted to guidethe same in its movement. The bar 52 has secured thereto a roller 54movable in a cam groove 55 arranged in the face of the disk 44, adaptedduring the continued rotation of the said disk to oscillate the bar 51and thereby reciprocate or extend the plunger 49 for the purpose ofactuating the movable cutter which acts in conjunction with the cuttingedge of the stationary cutter 41 to sever the wire B after the formationof a barb.

The action of the movable cutter is in a straight line, rather than theold form of oscillating the same. The cutting edge of the said movablecutter is extended obliquely to the edge of the stationary cutter,producing a shear cut and gradually severing the wire B rather thanabruptly cutting the same, relieving the jar incident to the old form ofcutter', and obviating the necessity of having to remove the cutter sooften for grinding.

In the manufacture of a loose barb, such as intended by this machine andsimilar to the barb disclosed in the aforementioned patent, it isnecessary to kink, corrugate or expand one of the strands of theStringer wire, at a point where the same will coincide with the barb onthe other strand when the two are brought together and intertwisted toform the Stringer wire. To accomplish this end it is further necessaryto place the barbs on the strand A, and then retain them in suchpositions during the drawing out of the wire A and deliver the same to apoint where the barb of the one wire will coincide with the kink orcorrugation of the opposite wire. This is the work of the plunger 24which is projected along the wire A at the finish of each barb, carryingwith it the then formed barb, which will be taken up by a movablecarrier or traveler to be described. To hold the barbs in the positionon the wire in which they are fed and coiled, see Fig. 15, l provide aguide or finger 56 extending in the same longitudinal direction as theaxis of the coiling spindle and in advance of the same. The finger 56 issupported by a suitable support 56 a attached to the bed, and liesparallel and beneath the strand A as it is drawn from the coilingmember. Thus it Will be seen, as the finger 42 is moved out of the pathof the barbs on the strand A, the plunger 24 is caused to bereciprocated forwardly through the coiling head', shoving the barb alongthe strand A in advance of the end of the plunger, the coiled portion ofthe barb lying above the finger 56 and preventing its ends from'-clianging their lateral positions with reference to the longitudinalbearing of the strand A. Then the plunger makes its stroke and deliversthe barb in position to be taken up by the carrier to be described theplunger 1s retracted or withdrawn into the coiling member, and thefinger 42 assumes its original position in front of the coiling head.The operation of the disk 44 is such that when the iinger 42 isoscillated, its inner end is held in its lower position long enough topermit the plunger to be projected and withdrawn. The parts operatingthe feeding rollers 33 and the cutters are also timed to the operationof the finger and plunger, as will be apparent.

The carrier or traveler to which reference has been made consists of alink-belt or chain composed of the usual links 57 and 58, coupled bypintles 59, the said pintles passing through a sleeve 60 disposedbetween the opposite bars of the links 57. To the links 58 are suitablyattached gripping members, clamps or vises which comprise pivoted sec- Itions 61, which may be substantial duplicates of each other as shown.The preferred manner of pivoting the vises to the links 58, is bycasting with the opposite bars of the links 58 the blocks or lugs 62;although the blocks or lugs may be separate and attached to the bars ofthe links in a suitable manner. To the upper face of each of the blocksor lugs 62 is pivotally secured at 62L the clamping member or vise 61,formed with the inner depressed body portions 63, which approach eachother centrally of their links, but are separated apart a suitabledistance to permit the passage or insertion of one or more strands ofwire between the matching faces 64 of the said members. To the upperfaces of the members and in the rear of the pivotal points thereof iscarried a roller 65, adapted during the continuous movement of the beltor chain to travel through a contracted guide-way for the purpose ofdirecting the matching faces of the vises to approach each other andfirmly impinge or grip the body of a wire or wires carried between thesame, serving as a pull-out for the strand A through the coiling memberand the strand C which together with the strand A forms the twistedstringer wire.

The belt or chain travels around a sprocket wheel 66 carried by a shortshaft 66L journaled in a boxing or support 67 attached or secured to thebed; also around a driving sprocket wheel 68 carried by a shaft 69 journaled in boxings 7 O supported by the said bed, to and aroundsprocket wheels 71 and 71a carried by short shafts 72 and 72l journaledin bearings of a pivoted frame, and

` K from the last mentioned wheel 72a to and around an idler wheel 73and to the first mentioned sprocket wheel 66. The manner of impartingpower or movement to the said carrier, is through a bevel gear 74carried on the power shaft 3 which intermeshes with a bevel gear 75which is loosely carried on the shaft 69. The bevel gear 75 isconstructed with a gear wheel 76 made integral therewith, and loose onthe said shaft 69, the same meshing with a gear wheel 77 carried by ashort shaft 77at journaled in an extension of the boxing 6. On the shaft7 7a is carried an additional gear wheel 78, which may be made integralwith the wheel 77, and the saine meshes with a gear wheel 79 fLXedlysecured to the shaft 69. The intermediate gearing just described betweenthe shaft 3 and the shaft 69 is provided to impart rotation in thedesired direction to the carrier.

The movement of the carrier and the vises thereof is horizontal,vertical, and horizontal again, to properly receive and convey thestrand A and its barbs from the coiler and convey the same to a positionfor receiving the strand in which the kinks or corrugations are formedand directing the same to a wrapper or spool revolubly mounted in themachine frame beneath the bed and coiling spindle. The upper run of thecarrier is positioned so that the depressed portions of its grippingmembers or their matching faces lie approximately in the same horizontalplane with the longitudinal axis of the coiling spindle, and the innerend thereof is positioned so that the gripping members, as they moveinto position will receive the barbs as they are projected by theplunger 24 5 and the free ends of the barbs drop into the depressedportions 63 ofthe opposite sections 61. The upper horizontal run of thecarrier travels between guiding frames or bars 8O and 80a forming arun-way for the carrier. The bar 80 is supported by studs or bolts 81from a frame 82 and springs 83 are coiled around the studs or bolts 81to yieldingly hold the bar 8O in position to partially close thesections 61 through the action of the rollers 64 which engage the wallsof the bars 8O and 80a, but not sufiiciently to cause the faces of thesections 61 to clamp the body of the wire A, the springs also yieldingto the action of the sections 61 as they travel through the run-wayformed by the bars 8O and 80a.

Above the horizontal run of the carrier and extending longitudinallythereof is disposed a covering plate or guide 84, so positioned that thelower edge of the guide 84 lies between the matching faces of thesections 61, as seen in section in Figs. 12 and 13, preventing thedislodgment of the strand A and the barbs thereof. A similar plate orguide 85 is disposed above the vertical run of the carrier and like theplate 84 has its lower edge members 61 enter carried between thematching faces of the sections 61, and serves in the same capacity asthe plate 84.

The lower horizontal run of the carrier is composed of the side bars 86and 86a which. are contracted at a oint 87, so that as the etween thecontracted portions of the bars 86 and 86a the rollers 65 engaging theinner faces of said bars will swing the inner faces 64 of the sections61 towards each other and cause the said matching faces of the sectionsto Yfirmly grip, clamp or nnpinge upon a wire or wires passingtherethrough. The gripping of the wires in the run formed of the bars 86and 86a serves as a pulling-out mechanism for continuously drawing thewire A through the ceiling spin die and from the spools. rihe clampingof the wire or wires at this point, also serves to hold them at a pointfrom which the twisting process takes place as the Stringer is fed tothe spool upon which the completed barbwire is wound.

The bar 86u is adapted to be adjusted towards or from its opposite bar,and is also held in a lyielding position. A frame 88 is provided betweenwhich the bars 86 and 86L are supported, the latter carried upon boltsor studs 89, and intermediate the frame 88 and the bar 86a is disposed abar 90, also cai ried by the bolts 89, and on the bolts between the bar863L and the bar 90 are carried springs 91 to hold the bar 86a inyielding engagement with the rollers of the sections 61.

l. have provided for adjusting the position of the bar 90 to increasethe tension on the springs 91 for the purpose of more or less firmlyclamping the sections 61 on the wire or wires extending between theirmatching faces. This 1 accomplish by means of the adjusting screws 92passing through the frame SS and engaging the bar 90 in the manner seenin Fig. 14, which also shows the contracted runway and the sections 61clamping the wires as described.

Having described the feeding in of the strand wire A forming one of theWires of the completed barb-wire-stringer, and the feeding in of thewire B from which the barbs are formed and coiled upon the Wire A, Iwill now proceed to describe the second wire which, together with thewire A forms the completed stringer wire, the manner of feed ing in thesaine and the kinking or corrugating of the wire Where it coincides withthe barb of the strand A. This wire C, is fed from suitable spools, notshown, in like manner as the wires A and B, and is directed through theguide 31, around the wheel 32, and over the guiding sheave wheels oridlers 93 and 93a suitably supported from the bed,

and overy a sheave wheel or idler 94 supported by a bracket 95 securedto an extension of one of the frame parts 88 which is secured to andforms a part of the pivoted frame referred to above and here designatedas 96. 1rom the wheel 94 the wire C is directed between the matchingedges of a pair of disks 97 and 97 a revolubly carried on short shafts9S and 98a, the former journaled in the frame S8, while the latter isjournaled in a movable boxing 99 slidable in a groove or slot 100 in thesaid frame, and adapted to be adjusted by means of a threaded stem 101,between which and the boxing is carried a spring 102, providing ayielding contact between the faces of the disks 97 and 97 a. The disk 97is provided with a series of corrugations or indentations 103 in itsperiphery while the disk 97 a is provided with a series of lateralprojections, teeth or lugs 104 corresponding to the contour of thecorrugations 103 in the disk 97 and adapted to coact therewith. As thedisks are revolved, they act as a pull-out for the wire C and this feedsthe same to the lower run of the carrier and its clamps or vises, to befed with the wire A to the twister or wrapper and its spool. As thecorru ations 103 and the lugs 104 coincide a suita le corrugation orindentation D is made in the wire, which forms a loop to span acoincidin barb on the strand A when the wires A and meet in the lowerrun of the carrierw The movement of the carrier and the timing of itsclamps or vises is such that as the corrugations D of the wire C aretaken up by the vises of the carrier they lie upon one side of the barbson the wire A and coincident therewith. The wires A and C as they leavethe carrier are directed to a twister or wrapper 105 journaled at itsopposite ends in the supports of the bed and the said twister carries aspool 106, which is detachably mounted on a spindle 107. The spindlereceives its power from the shaft 10 through a train of gears 108, 109,110, the first carried by the shaft 10, the latter mounted on a shaft110a having a pinion 1 11 on its inner end meshing with a gear 112 onthe spindle 107. The gear 109 serves as an idler, being mounted on ashort shaft and interposed between gears 108 and 110 to impart thedesired rotation to the spool 106. The point of twisting the wires A andC to form the cable Stringer or completed barb-wire, is, at the point ofreleasing the wires A and C, from the carrier; and the same being firmlygripped at this point between the vises of the carrier insures a uniformand ready intertwisting of the two wires through the action of thetwister 105. Returning to the disks 97 and 97 a the same are rotatedthrough a train of gears from the shaft 72a, of the carrier. On thisshaft is carried a gear wheel 113 meshing with an idler gear 114, andthe gear 114 meshes with a second idler .115, which. meshes with a gearwheel 116 on the shaft 98, and the shaft 98 also carries a pinion 117which meshes with a pinion 118 on the shaft 98a, and in this 97 and 97a. The adjustment of the threaded stem 101 regulates the depth of thecorrugations D in the wire C, and thereby more or less firmly impingesthe wire C between the matching faces of the said disks.

It becomes necessary in operation, that as the spool takes up thecompleted stringer or barb-wire it be wound evenly at a certain tension.To accomplish this, the mechanism of the twister and spooler is suchthat the spool will revolve fast enough to take up all the wire when thespool is first placed in the twister and the wire begins to be woundthereon. Said spooler mechanism is controlled by a friction brakeoperated from the shaft 3 and controlling the twister; the samecomprises a 'lianged drum or disk 119 around which is carried a strap119, of suitable material, the opposite ends of which are pivotallyattached to a lever 120, at 121 and 121L upon the opposite sides of thefulcrum point 122 of the said lever. The upper end of the lever 120 haspivotally connected therewith an arm 123 which at its outer end ispivotally connected with a crank arm 124 forming part of a lever 125which is fulcrumed to the bed at a point 124B: The outer end of thelever has connected therewith a rod 125EL extending longitudinally ofthe machine and at its opposite end is pivotally connected to a crankarm 126 carried by a short stem 127 journaled in a bearing 127 a securedto the bed. To the stem 127 is also attached a crank arm 128, which atits lower end has pivotal connection with a link 129 secured to the endof the shaft 72a journaled in the frame 96, or otherwise suitablyconnected to the said frame.

As the wire is wound on the spool said friction mechanism partly slips,permitting the spool to revolve only as fast as wire is delivered to it.The slipping of the said friction mechanism is accomplishedautomatically through the action of winding the wire on the spool, whichnot only relieves the tension on the wire, but also the tension on thespool, which is sometimes crushed by too tightly wrapping the wire onthe spool. To retain this uniform tension both upon the wire and spool Ihave provided the pivoted frame 96 around which the carrier travels andby means of which the wires are fed to the twister. The winding of thewire on the spool draws the lower end of the frame 96 towards the end ofthe twister which imparts the desired movement to the brake mechanismthrough the connections described, and by a coil spring 130 on the rod125a which bears at one end against a lug 131 on the bed, through whichthe rod is carried, and a collar 132 carried on the said rod, the frame96 is alternately oscillated in opposite directions, as also the brakemechanism. By moving the rod 125l in opposite directions the lever 120is oscillated which 1 causes the strap 119*l to alternately brake andslip against the drum 119 of the twister, as is apparent.

The idler 73 previously referred to around which the carrier moves, iscarried on a bracket 134, the outer end of which is pivotally secured at135 to the frame 96. A yielding support is provided for the carrying endof the bracket 134, which consists of rods 135a supported at their lowerends by the frame 96 and their upper ends adjustably connected with theend of the bracket 134, a spring 136 suitably carried on the rodspermits the brackets to yield to the movement of the carrier, and theadjustment in the rods 135t adapts the adjustment of the position of theidler 73 to take up any wear and lost motion in the carrier, all ofwhich it is believed will be understood.

In brief, the operation of the machine to produce a twisted stringerwire, upon one of the strands of which is coiled a loose barb, is asfollows: A strand wire A is passed through the ceiling member 17 and thestem 23 and plunger 24 thereof, the said stem and plunger whilerevoluble with the member 17 is reciprocally carried therein, the memberadapted to be continuously rotated through a gear wheel 137 carried onthe driving shaft 3 and meshing with a gear wheel 138 on the member 17.Having described the stem and plunger as revoluble with the member 17,it is understood that as a variation the member may rotate around thestem and plunger while they remain stationary and have imparted to themreciprocal movement only. From the coiler the wire A passes between thematching faces of the sections 61 of the carrier, being carried alongthe upper run of the carrier, down the vertical portion thereof, alongthe lower horizontal run, and thence to the spool 106 of the twister.

The wire B from which the barbs are cut and coiled around the strandwire A, is passed between the feeding rollers 33, to the wire A, the pin22 of the ceiling head wrapping or ceiling the wire B around the wire A,when it is severed by the cutters 41 and 46 the finger 42 serving toretain the barb in position until after ceiling when the linger 42 isremoved from in front of the ceiling head and simultaneously therewiththe stem 23 with the plunger 24 is projected along the strand A carryingbefore it the formed barb, which is received by a pair of the visesections 61 which move forward with the barb carrying strand A andretain the barb in the positions on the strand placed by the plunger,until the second wire C of the Stringer is placed in position with itscorrugations D coinciding with the barbs, when the two wires aretwisted. As the bars are shoved forward on their carrying wire A, theyare short shaft or spindle 133, journaled in a vcc retained in theirformed positions by means of the guide 56, which prevents the barbsturning on their carrying wire when projected.

The second wire C of the Stringer is drawn forward by the rollers orwheels 97 and 97d which also corrugate the wire C at intervals, and thewire is directed to theelower run of the carrier and between thematching faces of the vises 61, the corrugated portions of the wire Ccoinciding with the barbs on the strand A, as seen in sections ol thecompleted stringer. The vises as they pass through the lower run of thecarrier are caused to clasp the barb carrying and corrugated wires,while that portion of the two wires in advance of the lower run of thecarrier and the spooler, is twisted into a cable Stringer wire.

It is obvious that various changes may be made in the detailconstruction and arrangement of the machine, and while I have elected toillustrate the machine as producing a loose barb, the elements asarranged herein might be modified to produce a iiXed barb, and I do notwish to be confined to the details as illustrated and described.

I-Iaving thus fully described my invention, what I claim and desire tosecure by Letters Patent of the United States, is
